FIG. 8 is an explanatory view for attaching an electronic component. FIG. 9 is an explanatory view for attaching an electronic component. When assembling the electrical junction box 1, first, the target block 7 and the adjacent block 8 are housed in the box body 3 as shown in FIGS. 2 and 7 to 9. The worker positions the target block 7 below the box body 3 as shown in FIG. Here, the target block 7 is positioned so as to oppose the non-overlapping area S2 in the mounting direction in the lower opening. Next, the worker inserts the target block 7 into the internal space 3a of the box body 3 from the lower opening, and positions the target block 7 in the non-overlapping area S2 as shown in FIG. At this time, the movement of the target block 7 in any direction in the internal space 3a is not restricted. Next, the worker moves the target block 7 from the non-overlapping area S2 to the overlapping area S1 by the slide mechanisms 9R and 9L. At this time, the movement of the target block 7 in the width direction and the attaching / detaching direction is restricted. Next, the worker positions the adjacent block 8 below the box main body 3 as shown in FIG. Here, the adjacent block 8 is positioned so as to face the non-overlapping region S2 in the lower opening in the mounting / removing direction. Next, the worker inserts the adjacent block 8 from the lower opening into the internal space 3a of the box body 3, and positions the adjacent block 8 in the non-overlapping area S2 as shown in FIG. At this time, in the locking mechanisms 10R and 10L, first, the two guide projections 86 are inserted into the two guides 35 from below, and then the first projection body 84 is placed on the first receiving body 33. Then, the second receiving main body 34 gets over the second protruding main body 85, and the second receiving main body 34 is inserted into the second protruding main body 85. In the regulation mechanisms 10R and 10L, the regulation protrusions 87R and 87L are inserted into the regulation receiving portions 74R and 74L from below. Thus, the adjacent block 8 is locked to the box body 3 by the locking mechanisms 10R and 10L in the attaching / detaching direction, and is arranged in the non-overlapping area S2. The target block 7 is connected to the adjacent block 8 by the regulation mechanisms 11R and 11L, and is arranged in the overlapping area S1. Next, as shown in FIG. 1, the worker locks the lower cover 4 to the box body 3 by a locking mechanism R1, and engages the first upper cover 5 to the box body 3 by a locking mechanism R2. Then, the second upper cover 6 is locked to the box body 3 by the locking mechanism R3. Next, the operator positions the electric connection box 1 in the vehicle interior space 300 and faces the vehicle structure 200 such that the first upper cover 5 overlaps the protruding portion 201 in the attaching / detaching direction. Then, the electric connection box 1 is installed by fixing the housing 2 to the vehicle component 200 using a fixing tool (not shown).

FIG. 11 is an explanatory view of removing an electronic component. FIG. 12 is a diagram illustrating the removal of the electronic component. FIG. 13 is an explanatory diagram of removing an electronic component. Here, a case where the target block 7 is removed to replace the target electronic component 72 will be described. First, as shown in FIG. 10, the worker removes the second upper cover 6 and exposes a part of the internal space 3a of the box body 3 to the outside, thereby exposing the adjacent block 8 to the outside. At this time, the first upper cover 5 cannot be removed because it faces the protruding portion 201 in the attaching / detaching direction. Next, the operator moves the first receiving main body 33 over the first projection main body 84 in the upward direction (see FIG. 2). As a result, in the locking mechanisms 10R and 10L, the first projection main body 84 is directed upward with respect to the first receiving main body 33, and the second projection main body 85 is positioned with respect to the second receiving main body 34. In addition, the two guide protrusions 86 can be moved upward with respect to the two guide portions 35, and the lock of the adjacent block 8 with respect to the box body 3 is released. Next, the worker pulls out the adjacent block 8 from the second opening 3c to the outside of the box body 3 in a state where the locking by the locking mechanisms 10R and 10L is released, and as shown in FIG. 8 is positioned outside the housing 2 to remove it from the housing 2. At this time, in the regulation mechanisms 11R and 11L, the regulation protrusions 87R and 87L come off from above with respect to the regulation receiving portions 74R and 74L, and the target block 7 can be moved to the non-overlapping area S2 by the slide mechanisms 9R and 9L. It becomes a state. Next, the worker moves the target block 7 located in the overlapping area S1 to the non-overlapping area S2 by the slide mechanisms 9R and 9L as shown in FIG. At this time, in the slide mechanisms 9R and 9L, the slide protrusions 31R and 31L come off from the front with respect to the slide receiving portions 73R and 73L, and the guidance of the target block 7 ends in the non-overlapping area S2. As a result, the target block 7 is not restricted in any direction in the non-overlapping area S2. Next, the worker pulls out the target block 7 from the second opening 3c to the outside of the box body 3 in a state where the guidance by the slide mechanisms 9R and 9L is completed, and as shown in FIG. It is detached from the housing 2 by being positioned outside the body 2. Thus, the target electronic component 72 to be replaced can be replaced for each target block 7 or for each electronic component. The worker positions the replacement target block 7 below the box body 3 as shown in FIG. Next, the worker inserts the replaced target block 7 into the internal space 3a of the box body 3 from the second opening 3c, and places the replaced target block 7 in the non-overlapping area S2 as shown in FIG. Position. Next, the worker moves the replaced target block 7 from the non-overlapping area S2 to the overlapping area S1 by the slide mechanisms 9R and 9L as shown in FIG. Next, the worker positions the adjacent block 8 above the box body 3. Next, the worker inserts the adjacent block 8 from the second opening 3c into the internal space 3a of the box body 3, and positions the adjacent block 8 in the non-overlapping area S2 as shown in FIG. At this time, in the locking mechanisms 10R and 10L, first, the two guide projections 86 are inserted into the two guides 35 from above, and then the second projection body 85 is placed on the second receiving body 34. The first receiving main body portion 33 gets over the first projection main body portion 84, and the first projection main body portion 84 is inserted into the first receiving main body portion 33. In the regulation mechanisms 11R and 11L, the regulation protrusions 87R and 87L are inserted into the regulation receiving portions 74R and 74L from above. Thus, the adjacent block 8 is locked to the box body 3 by the locking mechanisms 10R and 10L in the attaching / detaching direction, and is arranged in the non-overlapping area S2. The target block 7 is connected to the adjacent block 8 by the regulation mechanisms 11R and 11L, and is arranged in the overlapping area S1. Next, as shown in FIG. 1, the worker locks the second upper cover 6 to the box body 3 by the locking mechanism R3.

  As described above, in the electric junction box 1 according to the present embodiment, since the housing 2 overlaps the vehicle component 200 in the attaching / detaching direction in the overlapping area S1, the gap between the housing 2 and the vehicle component 200 is suppressed. be able to. In addition, since the target block 7 (target electronic component 72) can be arranged in the overlapping area S1, it is possible to suppress formation of a useless space in the overlapping area S1 in the internal space of the housing 2. . In addition, the second upper cover 6 can be removed, the target block 7 (the target electronic component 72) can be removed from the housing 2 through the second opening 3c, and the target block 7 can be placed again in the internal space of the housing 2. Thus, the target block 7 (target electronic component 72) can be replaced, and the in-vehicle space 300 can be effectively used.

  Further, since the adjacent block 8 (adjacent electronic component 82) can regulate the movement of the target block 7 (target electronic component 72) located in the overlapping area S1 in the sliding direction, the target in the internal space of the housing 2 can be restricted. The positioning of the block 7 (target electronic component 72) can be ensured. Further, the second upper cover 6 can be removed, the adjacent block 8 (adjacent electronic component 82) can be removed from the housing 2 through the second opening 3c, and can be arranged again in the internal space of the housing 2. Thus, the adjacent blocks 8 (adjacent electronic components 82) can be exchanged, and the in-vehicle space 300 can be effectively used.

  Further, since the target electronic components 72 are handled in units of the target blocks 7, the time required for replacing the target electronic components 72 can be reduced as compared with a case where a plurality of target electronic components 72 are handled individually.

  Since the wire harness 100 described above includes the electric connection box 1, the target block 7 (target electronic component 72) can be replaced, and the in-vehicle space 300 can be effectively used.

  In addition, although the electric connection box 1 according to the above-described embodiment has one target block 7 arranged in the overlapping area S1, the present invention is not limited to this. In this case, the plurality of target blocks 7 are preferably arranged in parallel in the sliding direction with respect to the box body 3. Thereby, when exchanging the target block 7 which is closer to the adjacent block 8 in the sliding direction, the target block 7 located deeper than the target block 7 to be exchanged together with the target block 7 to be exchanged, Removal can be suppressed.

  Further, an urging means may be provided between the target block 7 and the box body 3 in the sliding direction. The urging means is attached to, for example, the inner wall surface in the depth direction of the box main body 3 so as to face the side surface in the depth direction of the block main body 71, and in a state where the target block 7 is arranged in the overlapping area S1, The target block 7 is caused to act on the box body 3 by applying a biasing force in the front direction. This makes it easy to move the target block 7 located in the overlapping area S1 to the non-overlapping area S2 by the urging force of the urging means, so that the workability in replacing the target block 7 (target electronic component 72) is improved. Can be improved.

  The electric junction box 1 according to the present embodiment is mounted on the vehicle interior space 300 such that a part of the housing 2 on the rear side in the sliding direction overlaps the protruding portion 201 of the vehicle component 200 in the attaching / detaching direction. It is housed but is not limited to this. For example, the electric junction box 1 becomes a second area on the near side and a first area on the far side from the worker who replaces the target block 7 (the target electronic component 72) of the electric junction box 1 in the in-vehicle space 300. It may be accommodated as follows. In other words, the second area may be located on the side where the hand of the worker can easily reach, and the first area may be located on the side where the hand is difficult to reach. In this case, the first region does not have to overlap with the protrusion 201 in the attaching / detaching direction.
